The v3 BOM keeps the v2 gate pitch, so the same shaft serves both versions; upgrading v2 to v3, your shaft carries over and it is the extrusion (now tapped) and the gear motor that change. The BOM is written for any gate count; vendors default to 4, 8 and 12, so we cut 6 and 9 as well.\u003c\/p\u003e\n\u003ch3\u003eSpecifications\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDiameter:\u003c\/strong\u003e 5mm, −0.02 \/ −0.03 (supplier drawing in the photos).\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlat:\u003c\/strong\u003e 4.3mm across the flat (0.7mm deep), full length.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e stainless steel, bright finish, not hardened.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eNot included\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e8mm smooth rods and the 2020 extrusion.
